There seem to be plentiful options for text chat servers, so I’m curious for those that self-host their own, what their preferences & experiences have been with them.
Also those mentioned in the title were just a few examples, if you run something else, e.g. Revolt or Mattermost or something else less popular, would be interested in reading about it!
AFAIK even without ircv3 history is possible - at least Unrealircd offers such an option (https://www.unrealircd.org/docs/Channel_history). However, I have only ever seen this utilized once, on a very small server.
Yep, as often, the extension of the standard comes from non standard features developed here are there (as you can see in the participating organizations block, most of the big names are working on this). The difference in ircv3 is that you can expect to see all those features everywhere, instead of having this software implementing this feature, that other one having that other feature, and you have to choose which one is the most important for you. Basically, it’s a rebase of the standard. :)
